Protognathosaurus oxyodon

† Protognathosaurus oxyodon was a sauropod dinosaur from China. A herbivore dinosaur of the Middle Jurassic, it inhabited the terrestrial ecosystems of this region. Fossil material documents its morphology and provides data on Mesozoic faunal diversity.

Diet & Feeding

Herbivore

Protognathosaurus oxyodon was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Middle Mesozoic Era

Protognathosaurus oxyodon lived during the Jurassic Middle period of the Mesozoic Era, approximately 174,7 to 161,5 million years ago.

Dinosaur diversity continued to increase, with the evolution of large sauropods and diverse theropods. Stegosaurs first appeared, and the supercontinent Pangaea was breaking apart.
